The series Byzantium between Orient and Occident (BOO) is a publication of the Executive Board of the Leibniz ScienceCampus Mainz and is published by the RGZM.

The series serves as publication organ for the research programme of the Leibniz ScienceCampus Mainz that studies Byzantium, its role as bridge between East and West, and cultural transfer and reception processes from Antiquity to modern times. The methods and research subjects of the various disciplines dedicated to Byzantium are brought together across traditional disciplinary boundaries in order to take a comprehensive historical and cultural approach to research into Byzantium and its material and immaterial culture.
